Tesco has reduced the price of women’s razors to match the lower price men pay for the product at its store.

It comes after the retailer was criticised last year, along with the other big four supermarkets Asda, Morrisons and Sainsbury’s, for ‘sexist pricing’ on many male and female products of the same brand and size.

An investigation carried out by The Times newspaper showed that women and girls were paying on average 37 per cent more than male customer for similar products, including clothes, beauty products and toys.

Investigation by The Times found that high street stores are charging women up to twice as much as men for similar products.

In the case of its own brand razors, Tesco was charging twice as much for a packet of women’s razors, compared to the men’s.

The retailer claimed the previous price inequality was due to the fact that male razors were produced and sold in significantly higher volumes, which reduced the price it pay for them.

The Fawcett Society, which campaigns for gender equality, called on the big Four to review their pricing policies after it found disparities of up to 56 per cent on supermarket branded products for women, such as shaving cream and spray-on antiperspirant deodorant.

In a letter to the Labour MP Paula Sherriff published on the Guardian, Tesco said: “Following an internal review and discussions with our suppliers, we have acted on concerns about the difference in price of our female and male disposable twin-blade razors”.

“However, following an internal review and discussions with our suppliers, we have acted on concerns about the difference in price of our female and male disposable twin-blade razors, in line with our commitment to ensure consistently low, simple and affordable pricing,”

“We have aligned the prices of these products so that the male and female razors are the same price per unit. We have done this by reducing the cost of the women’s razors and keeping the cost of the men’s razors the same.”
